[Bug 405120] Re: resume from suspend doesn't work (powers off instead) for various Acer Timeline laptops

[Jakob Kartschall]

** Description changed:

  Resume from suspend (to RAM) doesn't work (powers off instead on resume,
  didn't touch the power button) for Acer Aspire 3810T and Acer Travelmate
  8371/8471/8571 Timeline (and maybe more).
  
  WORKAROUND: Add the i8042.reset=1 kernel parameter in GRUB. To do this, change the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub to look like
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset=1"
  and execute "sudo update-grub"
+ 
+ Seems to working for (probably for other variations too) :
+ Acer Aspire 3810T / 3810TG/3810TZ
+ Acer Travelmate 8371G / 8371 / 8471
+ Acer Aspire 3410T
  
  Core 2 Solo (or Duo, both have this problem) ULV, Mobile Intel® GS45
  Express Chipset, Intel Wifi 5100.
  
  I have tried 9.04, 9.10 alpha 2 and 3, kernels 2.6.28 to 2.6.31, all
  32-bit. BIOSes 1.04 and 1.08 (latest). Nothing works.
  
  There is a single isolated report of suspend working with 64-bit 2.6.30.

  Suspend seems to work perfectly, but when a key is pressed to start
  resuming, the machine seems to start back up, but automatically powers
  off afer a few seconds (screen didn't come back up).
  
  Using the "resume-trace" procedure described here does not yield any
  matches. Unloading all non-essential modules in single user mode doesn't
  fix it (used /etc/acpi/sleep.sh to initiate suspend).
  
  Suspend is initiated through gnome-power-manager, but I don't think
  that's the problem.
  
  What else can I try?
  
  Thanks!
